Approval of an American National Standard requires verification by ANSI that the requirements for dueprocess, consensus, and other criteria have been met by the standards developer.
Consensus is established when, in the judgment of the ANSI Board of Standards Review, substanialagreement has been reached by directly and materially affected interests. Substantial agreement meansmuch more than a simple majority, but not necessarily unanimity. Consensus requires that all views andobjections be considered, and that a concerted effort be made toward their resolution.
The use of American National Standards is completely voluntary; their existence does not in any respectpreclude anyone, whether he has approved the standards or not, from manufacturing, marketing, pur-chasing, or using products, processes, or procedures not conforming to the standards.
The American National Standards Institute does not develop standards and will in no circumstances givean interpretation of any American National Standard. Moreover, no person shall have the right or authorityto issue an interpretation of an American National Standard in the name of the American National Stan-dards Institute. Requests for interpretations should be addressed to the secretariat or sponsor whosename appears on the title page of this standard.
CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time. Theprocedures of the American National Standards Institute require that action be taken periodically to reaf-firm, revise, or withdraw this standard. Parties interested in American National Standards, may receivecurrent information on all standards by calling or writing the American National Standards Institute.NOTICE ON FORMAT AND STYLE: The format and style of this document differs from ANSI style asspecified in the ANSI Style Manual for Preparation of Proposed American National Standards.

Scope
This standard is intended to provide a common basis of mechanical tests for evaluating the safety,durability, and structural adequacy of storage and desk-type furniture intended for use in the smalloffice and/or home office. The styling, marketing and chain of distribution for these products areintended to address usage in a residential, home office or small office environment. These productsmay be completely assembled, partly assembled or totally unassembled (often known as RTA or“ready to assemble”), when they leave the point of manufacture. These partly assembled and RTAproducts are designed to be assembled by the end user.
This standard defines tests used to determine acceptability of the product for the intended andreasonably foreseeable uses of the product. It specifies acceptance levels to help assure reason-able safety and performance independent of construction materials, manufacturing processes, me-chanical designs, or aesthetic designs.
The acceptance levels prescribed in these tests are based on the actual field and test experience ofThe Business and Institutional Furniture Manufacturer’s Association (BIFMA International) mem-bers. These tests are not intended to assess a product that has been in use in the field.
Reasonable safety of the product shall be considered the manufacturer’s responsibility only to theextent that the product is assembled and used in accordance with the original manufacturer’sinstructions. The assembler must follow the manufacturer’s instructions to ensure the productperforms as designed.

GeneralTypes of Tests
The testing and evaluation of a product against this standard may require the use of materialsand/or equipment that could be hazardous. This document does not purport to address all thesafety aspects associated with its use. Anyone using this standard has the responsibility to consultthe appropriate authorities and to establish health and safety practices in conjunction with any appli-cable regulatory requirements prior to its use.
The types of tests employed fall into the following general categories:
a) static load applications;b) dynamic load applications;
c) endurance or durability cycling tests.
It is not intended that all of the tests in this standard be conducted on a single unit. The tests may beperformed on a series of units at the discretion of the manufacturer. It is the intent of this standardthat all units shall be capable of meeting all of the applicable tests. Only worst case conditions (i.e.,size and construction) need to be tested for a specific unit type. When a test requires a functionalload and a proof load be applied as part of the test criteria, the functional and proof loads shall beapplied to the same extendible element or unit.
SMALL OFFICE HOME OFFICE FURNITURE - TESTSAt least one extendible element of each type, as applicable, per unit shall be tested. It is not neces-sary to repeat the tests for a particular type of extendible element because more than one is pro-vided as part of a unit. Similarly, this rule of testing a singular item also applies to unit leg assemblieswhen these items are of identical materials and construction.
10ANSI/SOHO S6.5-20013.2
Tolerances
Test tolerances, unless otherwise specified, shall be:
•Test Weights, forces, velocities, and time, ± 5%•Linear measurements, ± 1.5 mm (1/16 in.)•Angles, ± 5 degrees
•Level, within 5 mm per meter (1/16 in. per linear foot)•All cycle requirements are minimums.3.3
Manufacturer’s Instructions
When a manufacturer provides specific assembly, moving/handling or loading information, cautionlabels, or recommended maintenance adjustments that may be required in order to keep the productin good operating condition, these instructions shall be followed during testing unless otherwisespecified by test procedures.

A typicalloading material could be 721 kg/m3 (45 lb./ft.3) industry standard particleboard or typical boundcopier paper. The loading material size may be adjusted to accommodate the size of the extendibleelement to be tested. If necessary, up to 15% of the weight may be made up of higher density platesplaced on edge centered between the other loading material. The loading material shall be placedon its edge to minimize deflection of the extendible element bottom. Note: Higher density materialsmay be used for proof loads.3.4.3 Loading - General Guidelines - Dynamic testing of extendible elements with bottomsupported loads — (See Figure 3a and 3b) Note: Where extendible elements have the capability of supporting loads on the bottom and inhanging folders, test in accordance with 3.4.3. The clear space within an extendible element shall be loaded using the materials specified in Sec-tion 3.4.2. The loading material shall be uniformly distributed front to rear, side to side and not lessthan 70% of the clear height. The gap in the front and the gap in the rear shall each be 25 mm ± 6mm (1.0 in. ± 0.25 in.). The loading materials may be adjusted with the use of rigid materials (suchas rigid foam, steel, etc.) in order to maintain the specified front and rear air gaps. The front andrear air gaps are to be free of any materials. See Figure 3a for extendible elements which aredeeper than wide. See Figure 3b for extendible elements which are wider than deep.3.4.4 Loading - General Guidelines - Dynamic testing of extendible elements for hangingfile supported loads (See Figure 3c and 3d) The loading material specified in Section 3.4.2 shall be placed in hanging file folders of the appropri-ate size.

One cycle consists of a forward, then a backward stroke of the machine.f) For units with caster and glide combinations, the non-castered legs may be raised a maxi-mum of 51 mm (2 in.) above the test platform (supported by the attachment device) duringthis test. 19.3 Test Procedure Cycle the device for 2,500 cycles.19.4 Acceptance Level There shall be no loss of serviceability. 87SMALL OFFICE HOME OFFICE FURNITURE - TESTSANSI/SOHO S6.5-2001FORCELOADEDSMALL OFFICE HOME OFFICE FURNITURE - TESTSFigure 20 - Pull Force Test 88ANSI/SOHO S6.5-200120Pull Force Test (See Figure 20)20.1 Purpose of Test The purpose of this test is to measure the force required to move an extendible element or door fromthe fully closed position to the fully extended position.20.2 Test Setup a)The unit shall be placed on a test platform, leveled, and secured against movement.b)Extendible elements other than equipment surfaces shall be uniformly loaded per Table 1. Load shall be configured per Section 3.4.2 (Figure 3a or 3b) if extendible element has abottom. Load shall be configured per Section 3.4.3 (Figure 3c) if extendible element doesnot have a bottom. Equipment surfaces shall be loaded to the functional load according toTable 1. Any latching mechanisms shall be disabled. Doors shall not be loaded for this test.c)The extendible element or door may be subjected to a one-time break-in period of 100 cycles. One cycle is defined as travel from 0 to 6 mm (0 to 0.25 in.) of the closed position to 6 mm (0to 0.25 in.) of the fully extended position and return to its original position. Horizontal reced-ing doors may be supported in a horizontal plane during this test. d)A force gauge or other force measurement device shall be attached to the center of the pull area. If more than one pull exists, test each pull area independently. 20.3 Test Procedure Measure and record the maximum force that will open the extendible element or door from its fullyclosed position to its fully extended position.20.4 Acceptance Level The force shall not exceed 50 N (11.2 lbf.).
